🐛 Bug

When someone attempts to install the move-cli with cargo install --path language/tools/move-cli , it will fail with package toml_edit v0.19.15 cannot be built because it requires rustc 1.66.0 or newer, while the currently active rustc version is 1.65.0

More context: I am following the move tutoriall

To reproduce

• clone the repo
• cd and then ./scripts/dev_setup.sh -ypt
• cargo install --path language/tools/move-cli

  Either upgrade to rustc 1.66.0 or newer, or use
  cargo update -p toml_edit@0.19.15 --precise ver
  where `ver` is the latest version of `toml_edit` supporting rustc 1.65.0

In the rust-toolchain file, change '1.65.0' to '1.67.0' before installing. It should work.
